I have a business idea. Where do I even start?

You have an idea. You like it. You've told a friend, maybe written it in your phone at midnight. What you don't have is a first step. This is not because you lack information. It is because the first step is uncomfortable, and research feels safer than asking a stranger for money. Here is what's true: no one starts a business knowing everything. They start by doing one small, uncomfortable thing. Then the next one. The knowledge you think you're missing — legal structure, funding, branding — comes later, and only matters once someone has shown they'll pay. You are not confused. You are afraid of finding out the idea doesn't work. Choose to find that out now, cheaply, instead of later, expensively. That choice is the whole first step.
